A commercial facility in Westminster, CA had a Carrier split-system heat pump that was struggling to maintain cooling. Our licensed HVAC service team responded quickly to diagnose this commercial heat pump repair issue and restore proper performance.
Diagnosing a Freon Leak in the Carrier System
Our certified HVAC technician performed a thorough inspection of the heat pump. We discovered a refrigerant leak, indicated by low pressure and frost on the evaporator lines. Using electronic leak detection, we pinpointed the source at the evaporator coil inside the air handler. A Freon leak in the coil severely reduces cooling and could damage the compressor, so an immediate repair was needed.
Evaporator Coil Replacement Under Warranty
The faulty evaporator coil needed replacement. Fortunately, the unit was still under Carrier’s manufacturer warranty, so the coil part was provided at no cost. Our team obtained the proper replacement coil and proceeded with the repair.
Step-by-Step Repair Process
-
Refrigerant Recovery: Safely recovered the remaining refrigerant from the system using approved equipment.
